I'd like to really understand FM stereo. I've read the description in the RCA Receiving Tube Handbook (RC-30) about a million times, and stared at the demultiplexing circuit. Iunderstand part, and I don't understand part. Here's what I understand:The IF's job is saturation--clipping, if you will. Take the selected station, and amplify it into clipping, to get rid of amplitude artifacts. Then do a frequency to voltage conversion. For mono FM, that's clear as a bell. But how can a tuner dig out a supressed 19/38 kHz AM subcarrier after the main carrier has been clipped as hard as possible? Clearly, that's what's done, and dang if I understand how. Can someone explain?
